Subject: [PATCH] doc: Fix example with __next__() in PL/Python function

Per PEP 3114, iterator.next() has been renamed to iterator.__next__(),
and one example in the documentation still used next().  This caused the
example provided to fail the function creation since Python 2 is not
supported anymore since 19252e8ec93.
